WebIn 1977, an experimental group at Fermilab led by Leon Lederman discovered a new resonance at 9.4 GeV/c 2 which was interpreted as a bottom-antibottom quark pair and … The up quark or u quark (symbol: u) is the lightest of all quarks, a type of elementary particle, and a significant constituent of matter. It, along with the down quark, forms the neutrons (one up quark, two down quarks) and protons (two up quarks, one down quark) of atomic nuclei. It is part of the first generation of matter, has an electric charge of +2/3 e and a bare mass of 2.2+0.5 −0.4 MeV/c . Like all quarks, the up quark is an elementary fermion with spin 1/2, and experiences all four fundamental i…

WebThe Strange Quark. In 1947 during a study of cosmic ray interactions, a product of a proton collision with a nucleus was found to live for a much longer time than expected: 10-10 seconds instead of the expected 10-23 seconds! This particle was named the lambda particle (Λ 0) and the property which caused it to live so long was dubbed "strangeness" … WebApr 7, 2024 · quark, any member of a group of elementary subatomic particles that interact by means of the strong force and are believed to be among the fundamental constituents of matter. Quarks associate with one another via the strong force to make up protons and neutrons, in much the same way that the latter particles combine in various proportions … closed scroll
